NATURAL CONVECTION AND AIR FLOW PATTERN IN A PARTITIONED ROOM WITH TURBULENT FLOW.

Author(s) : HAGHIGHAT F., JIANG Z., WANG J. C. Y.

Summary

THE PAPER DISCUSSES THE USE OF THE KINETIC ENERGY OF TURBULENCE/TURBULENCE DISSIPATION RATE TWO-EQUATION TURBULENCE MODEL TO SIMULATE NATURAL CONVECTION OF HIGH RAYLEIGH NUMBER IN A PARTITIONED ENCLOSURE. THE AIR FLOW IS CONSIDERED TO BE THREE-DIMENSIONAL OWING TO THE ASYMMETRY OF THE ROOM CONFIGURATION. THE PREDICTIONS OF THE MODEL ARE COMPARED TO AVAILABLE EXPERIMENTAL AND THEORETICAL RESULTS ; GOOD AGREEMENT IS OBTAINED. THE STUDY ALSO DISCUSSES THE EFFECT OF DOOR HEIGHT AND LOCATION ON THE PATTERN OF AIR FLOW AND TEMPERATURE: THE FLOW PATTERN IS QUITE SENSITIVE TO THE VARIATIONS OF DOOR HEIGHT AND LOCATION, WHILE THE CONVECTIVE HEAT TRANSFER RATE IS ONLY SENSITIVE TO VARIATION OF DOOR HEIGHT.
